To aZZ whom itmay concern."

Be it known that I, EDWARD A. UEHLING, a citizen of the United States: of America, and a resident of Passaic, Passaic county,'New Jersey, have invented certain new and useful Improvements in Annealing Apparatus, of which the following is a specification, illustrated by the accompanying drawings.

The casting of slag-or cinder from blastfurnaces into the form of brick or buildingblock has proved tobe' a very useful and remunerative way of disposing of this by-prodnot; but owing to the cost of manufacturing these brick or blocks by the methods heretofore in use, which necessitated frequent handling and very considerable time,to'say nothing ofthe expenseof running a separate furnace to heat the annealing-ovens, this method of disposing of the slag has not been much used.

The object of this invention is to overcome the above-mentioned and other difficulties and to enable the production of the brick or building-blocks in' a rapid and economical manner.

' In the device here shown the molding of the brick or building-blocks and their annealing is carried out-at one and the same time, whereby many-advantages are attained, besides which thebricks are annealed by means of their own latent heat.

This improved apparatus is shown as used in conjunction with an annealingfurnace, Where brick or blocks of cinder or slag are made, but it is no way limited to use with the furnace shown, for, as will hereinafter be described, the annealing process can be carried out without the use of any furnace whatsoever. i

The annealing-carbconsists of an ordinary flat-car suitably mounted on Wheels to run upon the tracks or ways 0; The. bottom of this car is coveredwith a layer of fire-brick or other suitable fireproof material (Z. Upon thisfloor is erected an open box'compos'ed of metal plates 6. The ends of each of these plates are provided with thelugsf. Each of theselugs have tapering holes it within them adapted to "receive the wedges. g. In this .manner when the plates a are placed in an upright position, so that their edges overlap one another, and the wedges g'are driven into the holes h thebox becomes'rigid and stands upright upon the flooring d. Within the box is then placed an open frame, which is composed of four separate plates Z, extending the height of the box. Each of these plates is provided with braces mto hold them in position away from the sides of the box. With in the frame thus formed are placed the longitudinal plates and the short transverse plates j, which are secured to the open frameby means of projections upon the plates Z, which cooperate with recesses in the plates 1' and Z0.

The'longitudinal and transverse plates are se- .cured one to the other in a similar manner. This invention 1s by no means limited to this particular manner of fastening the plates to each other, as any means may be adopted to attain this result, the object being to have the plates easily and readily removable, so that the plates and the box itself maybe taken comassembled.

Near the upper portion of the plates j are projecting beads 25, cast integral with the plates. These beads extend the entire length of each pletely apart and the parts again readily reof the transverse plates j and are adapted to hold the horizontal plates at, as shown in Fig.

3. These horizontal plates u are rectangular in shape and adapted to cover each one of the rectangular openings formed by the plates and k. Each of the platesu is'provided with 7a, which plates are retained in any desired fixed position, either by the method shown or in any other way best suited. The moltenslag or cinder is then poured into the box, the molten matter filling all the openings between the transverse and longitudinal plates to a height approximately the same as the height of the beads t, the plates 14 are then put in position, and the molten slag is then poured between the braces m until all the interstices between the braces are completely filled. It will therefore be seen that by means of the plates Z and the braces m it is possible to obtain a covering for the annealing-blocks,

which has the same amount of heat as the blocks themselves, and therefore will prevent the blocks from cooling too rapidly by having these coverings brought directly. in contact with the outer air. The orifices w in the center of the plates a are adapted to allow any of the molten slag to rise above the height of the beads t without dislodging the plates.

In conjunction with this annealing-ear is shown a furnace in which it may be used; but, as before stated and as will be seen by the drawings, the process of annealing can be carried out without the use of any other means than the car itself.

In Fig. 1 is shown a cinder-car a, adaptedto transport the slag from the blast-furnace and also to discharge the slag into the annealing-car b.

Adjacent to the cinder-car a is the shed a, through which runs the tracks or ways 0, on which the annealing-car is carried. Within the shed and bridging the track 0 is the annealing-furnace 0. (Shown in Fig. 1 partly broken away.) This furnace is open at both ends to permit the car 6 to travel through it from end to end. Suspended in any suitable manner within the shed is the crane p, which travels transversely across the shed, besides whichit is capable of longitudinal movement along the entire length of the shed a. Parallel to the track 0 and within the shed a are two other tracks q and 4', the track r extending outside of the shed to the point where the bricks or building-blocks may be conveniently delivered when annealed- Upon these tracks (1 and r run flat-cars adapted one to receive the component parts of the box on the annealing-car and the other to receive the annealed blocks or bricks.

The operation of this device is as follows: The slag carried in the cinder-car a is brought into the position shown in Fig. 1 and its contents are discharged into the annealing-car Z). The card thus filled is then run along the track 0 either by gravity, by having the track in.- clined, or by any other appropriate device until the car is passed into the furnace 0 and assumes a position within the furnace, as shown in dotted lines in Fig. 1. Other similar ears are then filled and passed into the furnace until the furnace is filled with these annealing-cars. The length of the furnace is proportional to the time which the annealing process takes and to the length of the cars that is to say, that if, for example, the bricks can be annealed in twenty-four hours and the output of slag is ten cars for twenty-four hours, each car occupying ten feet of track, then thelength of the furnace need be one hundred feet to accommodate such an output. VVhenthe material in the first car has been annealed, the car is run out of the furnace under the traveling crane 7). The wedges 1 are removed and the various plates forming the box upon the car are carried by the crane and set upon the flat-car on the track g. The crane then lifts from the ear 7) the annealed bricks or blocks and sets them upon the flatcar on the track 1 which transports them to where they are to be delivered. The car on the track 1 loaded with the various parts of the annealing-box, is then moved to a more convenient position near the cinder-car, the crane lifts the frame of the annealing-car and carries it to aposition adjacent to the car carrying the parts of the box, and the box is readily reassembled upon the car 7/ and once more is placed before the cinder-car in a position to be refilled, and the operation repeated.

The plates composing the sides of the box forming the annealing-car and the various partition-plates within the box are preferably made of cast-iron, cast-steel, or other suitable material that will retain its position without warping when subjected to the heat of the molten slag.
